Water Flow Regulators

The Advantages of our Water Flow Regulators

EPDM O-ring seals are heat and water resistant.

Housings molded of reinforced polyphenylene oxide for tough industrial use.

Our sight tube is polyamide 12 which is superior,compared to competitor‘s polycarbonate, when highertemperature water is used. Competitors charge extra for the better material. On our unit it is standard.

Reference marks are molded in, not painted on.

Enlarged water passages minimize flow restrictions, deliver increased flow volume through the molds and enhance heat transfer performance. In fact, pressure drop from our regulators is about half that of competitive units. That‘s an important difference if plant water pressure is low.

WITTMANN Flow Regulators include precision, threaded brass inserts (Series 301) or brass sockets (Series 101) for your water hose connections, unlike poorly designed regulators which use leak-prone molded threads which can strip easily.

All units are 100% leak tested before shipping.

Thermometer is located directly in the water flow giving a more precise reading and a quicker reaction to changes. Competitor‘s thermometers are not in the water flow path.

Option: Dry-Out Valve

Allows complete clean out of regulator sight glasses.

Easier to Clean

The water flow regulators are exceptionally easy to clean. A top access cap is simply removed and a brush (provided) quickly cleans the tubes without removing them.

Competitor‘s regulators include a large diameter valve for the main seat which means regulation is not precise. With a very small mo-vement of the handwheel, the valve is opened almost completely. Our units have a smaller diameter seat which allows better adjustment of flow.

Using brass valves and brass connections isresulting in highest corrosion resistance.

Easier to Remove

Individual sight tubes can be easily removed and reseated, if necessary. Precision O-rings positively seal the sight glass, absolutely leakproof even under maximum loads.

The optimum flow regulator for large injection molding and blow molding machines.Its low pressure drop makes it suitable for highest flow volumes. However, by means of a special design of the regulating valves, excellent regulation and accurate repro-duction of cooling water volume and temperature in the different mold circuits can also be achieved for low flow volumes.

The Series 101 and 301 Water Flow Regulators can be supplied with shutdown solenoid valves.

Valve Z: Central shutdown of several mold circuits.

Application: e.g. controlled by the cycle of the injection molding machine. When the injection cycle is stopped the cold water flow is shutdown to avoid condensation on the mold cavities.

Valve E: Shutdown of cooling water in individual mold circuits.

Application: e.g. chilled cores The valve can also be controlled by a temperature controller from the injection molding machine for mold temperature control.

Optional: Solenoid Valves

Accurate Control and Perfect Process Monitoring Precise, stable mold temperature through automatic control. The development of this unit is based on many years of applied experience. Microprocessor controlled accuracy ± 1 C°. Up to 8 zones can be controlled individually. Storage of setup data for 7 different molds. A tolerance window can be set on the display. If the temperature exceeds the tolerance.

a buzzer or alarm contact is activated. Serial interface for data transfer to IMM standard. Secures the quality of the molding process by perfect temperature

control and monitoring. Plunger type solenoid valves with large seat diameter ensure operation even with poor water quality.

FLOWCON: Automatic Flow Regulator

Mold Temperature Control by FLOWCON Closed circuits reduce the period for warming up the mold. Continuous control ensures a water flow when cooling is needed and prevents cooling down the mold when production is interrupted.

Mold Temperature Controlled by Standard Water Flow Regulator Water flow is adjusted manually until the set value of mold temperature is reached. When production is interrupted or when water pressure is changing the mold temperature will change.

User Friendly Display Green LED shows that valve for the circuit is open RED LED shows that temperature is out of tolerance.
